One of the key differences is the reduced level of complexity when building a decentralized application. There’s no need to worry about infrastructure, server configuration or database maintenance. Overall, there are fewer dependencies. We can focus on a single problem and optimize to solve that problem really, really well. In the long run, this leads to less operating costs.

"...email has stayed, and has largely stayed decentralized, and from that — its ubiquity and lack of central authority — email has become one of the most boringly powerful publishing platforms around."
